Soundproofing yards and handling external noise

Outdoor noises may come from all types of directions simultaneously and might have many sources. They can also be reflected all over the space. People have a tendency to look at what they think are the source and imagine that the sound is travelling along a straight line from the source to their yard. The truth is it is possible that sounds have deflected, bouncing off buildings and other objects, reaching at your yard amplified and from a different direction to the source. The amplification which happens is not different from sound amplification, which happens when a murmur has passed through a wind instrument and emerges at the other end as a trumpet blast. Hence, your first step is to recognize the source of the issue and the path that it is taking to get to the yard.

It may be possible that a nearby business or industry is surpassing noise levels that adhere to decibel chart of common sounds or the duration or operating at inappropriate times of the day. Sometimes, you can solve the issue by just raising the problem with the proprietor in a friendly way. It might also pay to check with your municipal council and ensure that your noisy neighbors are not breaking local laws. People are frequently surprised to learn that there are many laws protecting residential facility. I have seen laws which limit the use of air conditioners after a definite time, prohibit leaf blowers and even outlaw pets such as barking dogs and roosters.

Having exhausted logical commonsense approaches to lessening the noise of a chassis dynamometer system, you have a couple of options for solving the issue. The first option is create some type of acoustic barrier in the yard.

An air tight yard

It is impossible to make a yard completely airtight. You will always have to handle flanking sound. Flanking sound is the sound which wraps over, under or around your soundproofing structures. All these principles of internal sound barriers and sound absorption still apply outdoors.

Low frequency noise comes with a longer wavelength than high frequency and will need a denser and higher sound blocking panels. For instance, if you are facing truck noise, you would possibly require a higher barrier. In most cases, this is unrealistic or even against the municipal building regulations. Hence it may be recommendable to return indoors and work on your soundproofing there and be happy with a serene internal environment.

Watch for what you listen to

Just like all soundproofing problems, there are unlimited myths about external soundproofing. The most common one is the usage of shrubs and trees. Many property developments are noisy torture chambers and still there are blissfully happy people living the life of their dreams with fiberglass ceiling tiles.
